5 Dragon monsters with different Attributes
When this card is Link Summoned: Target 1 Level 7 or higher Dragon monster in your GY; Special Summon it, then equip it with this card. While equipped by this effect, the equipped monster gains 1000 ATK/DEF and cannot be targeted by card effects, also it cannot be banished while face-up on the field. When the equipped monster is destroyed by battle and this card in your Spell & Trap Zone is sent to the GY: Equip this card from your GY to the monster that destroyed it. While equipped by this effect, the equipped monster's ATK/DEF become 0, also its effects are negated and it cannot be Tributed or sent to the GY.

Honestly, for a Link 5, this seems kinda underwhelming. While it can spawn a big monster from the grave and give it some decent protection, or basically render an opponent's monster useless, that last effect is almost never going to go off since it needs your monster to be destroyed by battle, and considering whatever you summon with this is going to have close to 4000 ATK, that's not likely to happen. Also, the materials. 5 Dragon monsters with different Attributes? I expected something a bit more powerful considering this card is nearly impossible to summon. 

I'd change it to simply require 5 Dragon monsters, much like Five-Headed Dragon. Or maybe, some tweaks to the effect - Make it so the effect to equip an opponent's monster happens any time your dragon is destroyed, not just by battle, and let you choose the new target. Making that second effect not let the enemy monster be used as material might be better than just not letting it be sent to the graveyard - I believe that was your intention to begin with. Maybe letting the summon effect also summon a dragon from the hand as well as the graveyard is a good idea, too. Link 5 monsters aren't the easiest to summon, so don't be afraid to give it a more powerful effect.

Got me thinking, but it's a good question, thanks for the warning. And yes, what you said is correct, my goal was to make this monster not tribute or at least try to leave it on the field longer. But the fact that I wanted to leave, was that this would be an ultra rare monster card, still, I really feel that 5 dragon monsters of different attributes would be even good, because then the difficulty of summoning it would be higher, anyway that becomes more harder and not impossible... I think?
